    Default White Field Boss 31 (Iseki) ignition switch

    I think the ignition switch on this 1980s compact diesel tractor has failed. Anyone got a source for a replacement?

    There's no part number on the switch. It has four positions=off, on, glow and start= and five terminals on the back. The glow and start positions are spring-loaded. The terminals are numbered 30 (power from battery), 17, AC, 19 & 50. I think the 50 goes to the glow plugs. In the ON position and the START position, there's intermittent continuity between the power terminal and other terminals. Seems to be pretty good continuity to the glow terminal.

    Can anyone suggest a replacement switch?

    If my memory serves me correctly that sounds like the numbering on a kubota B7100 switch. I don't have one in front of me as I am at work now. If I remember I will check when I get home. I have a spare switch (If I can find it)

    OK-- found the switch
    17,19,30,50 and AC

    Quick look at my service Manual
    19 to glow plug indicator then to 17
    17 to glow plugs
    50 through the safety switch then to starter
    30 multiple connections must be power in from battery
    AC out to lights and hour meter (accessory)

    Sounds like the same switch you have on your tractor.
